From the current information, the new coronavirus is mainly based on dampness, pharmacologically speaking, Banlangen is not suitable for early prevention, and there is no clear evidence that Banlangen is effective in preventing the new coronavirus. For methods such as vinegar prevention, there is no clear evidence that vinegar is effective in eliminating the virus. At present, it seems that this new coronavirus is sensitive to heat, including 75% ethanol, chlorinated disinfectants, and hand disinfection, all of which can inactivate this virus, so it is not a very difficult virus to resist.
